Therefore, carefully perform the adjustment, being aware that the image quality of all future images will be
changed, when storing originals other than the one that is used for the adjustment.
Remarks
• If "HIGH QUALITY" is selected from among the "IMAGE QUALITY FOR BLACK" options and black-and-
white originals are scanned in the Auto color mode and stored in the e-Filing box (Scan to Box), this allows
them to be stored in the Gray scale mode rather than in the binary mode, and eventually provides better
halftones. The data will increase in size, compared to those in the binary mode.
• The adjustment of threshold values will be effective, only if "STANDARD" is selected from among the
"IMAGE QUALITY FOR BLACK" options.
